The remains of his son, William Wallace Lincoln, were also placed on the train, which left Washington, D.C., on April 21, 1865 and traveled to Springfield, arriving on May 3, 1865. Several stops were made along the way, in which Lincoln's body lay in state. The train retraced the route Lincoln had traveled to Washington as the president-elect on his way to his first inauguration, and millions of Americans viewed the train along the route. Lincoln's wife Mary Todd Lincoln remained at the White House because she was too distraught to make the trip; she returned to Illinois about one month later.
